Typifying fat tissue in calves

13.08.2003


Despite fat in meat being frequently associated with negative connotations for the consumer, it is an indispensable component in order to obtain quality meat. To better understand the metabolism of the fat in calf meat and to enable its possible modulation in future, Martín Alzón Aldave has presented his PhD thesis on the Development and metabolism of veal fat tissue in seven Spanish autochthonous breeds of meat-yielding calves.



Seven autochthonous breeds

Martín Alzón had two aims with this project. Firstly, to typify the fat tissue of both light weight calves (320 Kg live weight) and heavy weights (540 Kg live weight) from the main Spanish meat-producing breeds: Asturiana, Avileña, Morucha, Parda Alpina, Pirenaica, Retinta and Rubia Gallega. To this end he studied, amongst other factors, the amount of fat, the size of the adipoceres and the activity of the principal lipogenic enzymes of the internal fatty deposits and of the canal.


The results of the research show that calves from the Morucha, Retinta and Avileña breeds had the greatest quantities of fat in the four fatty deposits studied and at both weights at slaughter, while the calves from the Asturiana and Rubia Gallega breeds proved to be the least fatty.

Three types of fatty tissue

After the factorial analysis carried out on all the animals and with all the variables studied, Martín Alzón concluded that the 14 groups studied, i.e. the animals from seven breeds of both weights, can be classified into three groups. The first placed the Asturiana and the Rubia Gallega slaughtered at 320 Kg live weight together, characterised by a scant development of fatty tissue.

A second group, with an intermediate development of fatty tissue, include the Avileña, Morucha, Parda Alpina, Pirenaica and Retinta breeds slaughtered at 320 Kg live weight and the Asturiana and Rubia Gallega breeds slaughtered at 540 kilos live weight.

Finally, a third group was characterised by an intense fatty tissue development: the Avileña, Morucha, Parda Alpina, Pirenaica and Retinta breeds that were slaughtered at 540 kilos live weight.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
